2011-10-27 Harvest Harvested GLBRC G5 and G7 micro-plots (fertilizer and no fertilizer plots), all reps. Harvested with JD 7330 tractor using the 4 ft wide Kemper head and Wintersteiger biomass harvester weighing system. The middle 4' of each micro-plot was harvested. Plot weights were obtained from the on-board FRS Harvest Master computer weighing system, by Juniper Systems. Cutting height of plant stubble was 6 inches. Grab samples from each rep was placed in paper bags weighed for wet weight and placed in plant dryer and reweighed to determine percent moisture for each treatment and replication.
